PETER BENJAMIN BARNES, OF ELORESVILLE, TEXAS.

COTTON-GIN BREAST.

Specification of Letters Patent.

Application filed December 21, 1909.

Patented July 4, 1911.

Serial No. 534,314.

To all whom it may concern:

Be it known that I, PETER B. BARNES, a citizen of the United States ofAmerica, re-

siding at Floresville, in the county of WiL' son and State of Texas,have invented new and useful Improvements in Cotton Grin Breasts, ofwhich the following is a speci-l fication.

This invention relates to cottongins, and it has particular reference toa cottonv gin breast of improved construction.

Cotton gin breasts are usually constructed with an outward bulge inorder to promote land facilitate the tendency of the contents to formitself into a compact roll which is kept in a constant state of rotationby engagement with the rapidly rotating gin saws, the roll beingmaintained approximately at a constant size by fresh material suppliedfrom the feeder to compensate for the lint and seeds discharged from themachine.

The present invention has for its prime object to so construct the ginbreast that a direct pressure will be exercised upon the cotton roll inthe direction of the saws which will thus engage the lint with morecertainty and eiiiciency.

Further objects of the invention are to simplify and improve the generalconstruction and operation of a device of the character outlined above.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawing has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention may be resorted to when desired.

In the drawing,-Figure 1 is a vertical sectional view, showing as muchof a cotton gin of ordinary construction as is necessary to illustratethe invention, which is applied to said gin. Fig. 2 is a view inelevation,

showing the improved gin breast detached. Fig. 3 is a sectional viewtaken on the plane indicated by the line 3-3 in Figs. 1 and 2.

The invention has in Fig. 1 of the drawing been shown applied to acotton gin which may be of any well known and approved construction; 5designating the frame or casing, 6, the saw-carrying shaft, 7, one ofthe gin ribs, 8, one of the saws and 9, the rotary brush cylinder. Thegin breast 10 is of the conventional bulging shape, and it has beenshown as being provided adja cent to its upper edge with a flange 11constituting the front wall of the hopper 12 and adjacent to its loweredge with a flange 13 constituting the front wall of the spout 14through which the cleaned seeds are discharged.

The body of the breast is vertically corrugated, as clearly shown' inthe drawings, being provided upon its inner face with alternate ribs 15and grooves 16 of rolling or wavy form in cross section, the ribs beingdisposed intermediate the saws 8, which lat ter are thus disposed indirect alinement with the grooves 16.

It will be evident from the foregoing description when taken inconnection with the drawings hereto annexed, that when the device is inoperation the cotton roll contained in the gin casing will be subjectedto the pressure of the ribs upon the breast and that the tendency ofsaid pressure will be to force the yielding material of which the rollis composed in the direction 0f the saws by which the lint will thus beengaged more readily and efficiently than has hereto fore been the casewhere gin breasts of ordinary construction have been used. Owing to therolling or wavy form of the ribs and grooves composing the face of thecorrugated breast, the pressure of the saws transmitted through theelastic material of the roll will not cause any tendency of saidmaterial to stick or to bind, the surface presented to the roll beingsmooth and free from sharp corners or indentations of any kind whichmight cause binding, thereby retarding the operation.

The device is extremely simple, and it may be installed at a verymoderate expense upon gins of either roll fashion or modern constructionWith equally satisfactory grooves being in alinement With the gin l0results. saws.

Having thus described the invention, What In testimony whereof I aIiX mysignature is claimed as new is in prese-nce of two Witnesses.

In a cotton gin, a bulging breast plate cor- PETER BENJAMIN BARNESrugated upon its inner side to present a series of grooves and ribs ofrolling, Wavy Witnesses: cross section, said grooves and ribs being S.J. COLLIER, vertically disposed, -in parallel relation, the J. H. BROWN.
